NEW YORK -- Here are notes from press conferences by Sandy Alderson and Terry Collins reacting to the trade of Marlon Byrd, John Buck and cash to the Pittsburgh Pirates for Dilson Herrera and a player to be named later:
• The Pirates claimed both Buck and Byrd, meaning the Mets could only deal with that team.
• The timing was coincidental with the Matt Harvey injury, Alderson insisted. In fact, he said the players went on waivers last Friday and were claimed during the weekend, well before Harvey's Monday medical exam.
• Alderson did not make any overtures to Buck before the trade to see if he would entertain re-signing for 2014 to serve as Travis d'Arnaud's backup.
• As for trading Byrd now and not in July, Alderson said: "At the end of July, it was a 29-team market. In this case it was a one-team market, because both of these deals were pursuant to a waiver claim. That notwithstanding, the value -- at least our perception of the value in this instance -- was greater than the value at the end of July. And, of course, we were also looking at the 60 additional days of Marlon Byrd at the end of July versus about 30 [now]. So there were different factors involved, but we very definitely feel this was a better package for us than we could have obtained in July."
• Lefty-hitting Matt den Dekker will play a fair amount of center field, with Juan Lagares in right field on those days. Den Dekker, though, should share outfield duty with the righty-hitting Andrew Brown. Lucas Duda is being considered a backup first baseman at this point.
• The organization views Herrera as a second baseman. He will go to Savannah in the South Atlantic League. He already was playing in that league for West Virginia, even though he was young for that level at 19 years old. Alderson said: "He's got some power. He runs pretty well."
• Alderson said it is "unlikely" any more trades will materialize.
• The Mets expect to call up a third catcher in September. The logical candidates would be Francisco Pena and Juan Centeno.
• The trickle-up of promotions include Florida State League home run leader Dustin Lawley moving all the way to Las Vegas.
